Functions

func DedupPaths

func DedupPaths(paths [][]string) [][]string

func Equal

func Equal(a, b []string) bool

func GetExprsFromStmt

func GetExprsFromStmt(stmt ast.Stmt) []*ast.CallExpr

TODO: Lots of repeated code that we can refactor here Further, this is likely not sufficient if used for more general purposes (outside wally) as there are parts of some statements (i.e. a ForStmt Post) that are not handled here

func GetFormattedPos

func GetFormattedPos(pkg *ssa.Package, pos token.Pos) string

func GetFuncSignature

func GetFuncSignature(expr ast.Expr, info *types.Info) (*types.Signature, error)

func GetFunctionFromCallInstruction

func GetFunctionFromCallInstruction(callInstr ssa.CallInstruction) *ssa.Function

func GetFunctionFromSite

func GetFunctionFromSite(site ssa.CallInstruction) *ssa.Function

func GetName

func GetName(e ast.Expr) string

func GetParamPos

func GetParamPos(sig *types.Signature, paramName string) (int, error)

func GetValueFromExp

func GetValueFromExp(exp ast.Expr, pass *analysis.Pass) string

func IsClosure

func IsClosure(function *ssa.Function) bool

func IsLocal

func IsLocal(obj types.Object) bool

func ResolvePackageFromIdent

func ResolvePackageFromIdent(expr ast.Expr, info *types.Info) (*types.Package, error)

ResolvePackageFromIdent TODO: This may be useful to get receiver type of func Also, wrong name, its from an Expr, not from Idt, technically

func ResolveParamFromName

func ResolveParamFromName(name string, sig *types.Signature, param *ast.CallExpr, pass *analysis.Pass) string

func ResolveParamFromPos

func ResolveParamFromPos(pos int, param *ast.CallExpr, pass *analysis.Pass) string

func ResolveParams

func ResolveParams(params []indicator.RouteParam, sig *types.Signature, ce *ast.CallExpr, pass *analysis.Pass) map[string]string

func SiteMatchesFunc

func SiteMatchesFunc(site ssa.CallInstruction, function *ssa.Function) bool
